Abstract

DE LEITO DE UMA UNIDADE PSA"<D>. Um processo PSA de separação de um fluxo gasoso que contém essencialmente oxigênio e nitrogênio, tal como o ar, por adsorção preferencial do nitrogênio em pelo menos um leito de espessura (e) de um material adsorvente de granulometria média (d) inserido em pelo menos uma zona de separação, no qual escolhe-se uma espessura (e) de leito de adsorvente tal que: 300 <242> 1000 <MU>e<MV> e <MU>d<MV> sendo expressos em mm. BED OF A PSA UNIT "<D>. A PSA process of separating a gas stream that essentially contains oxygen and nitrogen, such as air, by preferential adsorption of nitrogen in at least one bed thick (e) of a material medium-sized adsorbent (d) inserted in at least one separation zone, in which an adsorbent bed thickness (e) is chosen such that: 300 <242> 1000 <MU> and <MV> and <MU> d <MV> being expressed in mm.
